- multer
This application/site was created as a submission to a DevChallenges challenge. The challenge was to build an application to complete the given user stories.
- left many routes open - could add JWTVerifys to all routes vs just the mutate routes (post, put, delete)
- messages and channels are open - better to have a way to see the chat before signing in
- need another server (socket.io) ? to have chat group be realtime across users - don't think so - because useEffect will update the view when channels and messages change
- Promise.all() might be needed for multiple route calls in some functions - async - have to worry about order of results
- add helmet ?
- testing
- seeding the database vs using my hacky way of creating a welcome channel if it doesn't exist
- "select: false" in model vs removing field with .select('-password') vs removing field in populate call - what is best approach?
- password field may be sent back in some calls - intermediate step - password forwarded along with userInfo then removed later - should exlude first and then forward or overly concerned - password is hashed and protected by jwt
- can't pass two parameters to same route - express cant differentiate between them - need to add word in between i.e. /:channel/:id vs /:channel/id/:id
- channel controller has a very convulted route because of that and it could be cleaned up
- sorting with mongoose vs sorting response.data in the client - in React, use memo on the data.
- multer and controllers don't mix
- controllers considered an anti-pattern ?
- getting file path is difficult - fakepath issues - can't get the file to save - the folder will be created - dir name in multer middleware
- had issues with multer callback syntax - console.logs need to be inside functions inside callbacks
- Added fs unlink logic to remove photos that are no longer tied to user profiles
- Read about changes coming to Multer (2.0) so need to look out for that
- Profile pictures come from freepik. Check below for links - the majority of pictures belong to the same series.
- Added
public/uploadsto gitignore
